The technical principle is shown as the picture, which is similar to the SLA. And it also can used to scan different layer of materials. But the laser of SLS is CO2 laser, whose modeling materials are power. While it is processing, the power will be hated to a little lower than its melting point temperature, and then heat the power by controlling the laser beam to make it reach the temperature of sintering, so that it can be cured and bonded with upper layer. 

Molding Materials：PA or PA+GF, etc

Technical characters:

It has good mechanical properties, which can be used for functional test or small volume application.

High processing speed, high usage of material, high efficiency
